Dick,

The K3 will display higher values of SWR if you use the TUNE mode (hold the
XMIT/TUNE button). That will transmit a carrier and display the SWR in the
VFO A display area.

I don't know what the upper limit of this SWR display is, but I just tested
it into a deliberately mismatched load and got 13.2 : 1.
